Electrical Specifications
84 Datasheet, Volume 1
Notes:
1. Unless otherwise noted, all specifications in this table apply to all processor frequencies.
2. V
IL
is defined as the maximum voltage level at a receiving agent that will be interpreted as a logical low
value.
3. V
IH
is defined as the minimum voltage level at a receiving agent that will be interpreted as a logical high
value.
4. V
IH
and V
OH
may experience excursions above V
DDQ
. However, input signal drivers must comply with the
signal quality specifications.
5. This is the pull up/down driver resistance.
6. R
TERM
is the termination on the DIMM and in not controlled by the processor.
7. The minimum and maximum values for these signals are programmable by BIOS to one of the two sets.
8. DDR3 values are pre-silicon estimations and subject to change.
9. SM_DRAMPWROK must have a maximum of 15 ns rise or fall time over V
DDQ
* 0.55 ±200 mV and edge
must be monotonic.
